Notes: My employer at the time gave me this calculator after he saw my calculator collection on the web. It is a scientific calculator with a fluorescence display.

Noteworthy is the way it displays the minus, it uses the top segment of the leftmost display digit. Furthermore, a small "u" indicates something is stored into the calculator’s memory. Thanks, Jan Hurstjes.


A power adapter.
